I can't speak out of experience for Burnt Creek or the Misty Waters marina specifically but it might surprise people the kinds of fish that get into tiny creeks like that especially during high water. Would have to walk banks, watch the water, and blind cast it. Might require permission to walk if its private land. I always start with wooly buggers and clousers. Weightless if its shallow or if theres carp on top. Watch for wakes, tailing, or lips sucking on the surface, especially in foamy weed choked pockets. Wear sunglasses and watch for spooked fish as you approach water that you can see into. Carp are lazy and generally wont chase down a fly like a bass (though it happens). Land a weightless fly in front of them and slowly twitch it across their face. Either guess when they suck it in and strip set or see it.
Maybe theres pike or bass in it, I dont know. Just blind cast those streamers, bigger sizes depending on what you find in there. If theres bluegill, tiny poppers work.
Or just cast familiar lures until find you fish, and then swap to an appropriate fly. I dont know what to do in places I havent been but I do know how to guess at getting started to figure it out. Creeks are good for new casters cus distance isnt as important. But if the creek is clear or you cant reach a spot, distance casting helps.
